Sheridan is conducting a Canadian Film Center screenwriting workshop here after the fluffy white stuff, or more precisely, the lack thereof, last January cursed the original shoot in Toronto for his psychological thriller "Dream House." The Daniel Craig and Rachel Weisz-starrer is now set for reshoots in March 2011.

"We went to Toronto in January and it didn't snow one day that month. And the entire movie is set in a snow storm," he explained.

Even worse, in Connecticut, where the supernatural thriller for Universal Pictures is set, it snowed heavily from January to March last winter, Sheridan recalled.

The additional footage -- mostly snowy footprints and shots out of car windows -- was to be shot in Toronto this week.

But the reshoots have now been postponed to March after Craig couldn't get away from the set of David Fincher's "The Girl With The Dragon Tattoo" in Sweden at the same time that Weisz was free from the London set of Terence Davies' "The Deep Blue Sea."
